Overloaded operator handlers sometimes receive operands in reversed order, but Perl will notify the handler when it does so by setting the swapped argument to true.
<p>[doc://overload]:
<blockquote><p>Three arguments are passed to all subroutines specified in the use overload directive (with one exception - see nomethod). &#91;...] The third argument is set to TRUE if (and only if) the two operands have been swapped. Perl may do this to ensure that the first argument ($self ) is an object implementing the overloaded operation, in line with general object calling conventions. &#91;...]</blockquote>
<p>You probably disregarded that argument?
